This invention relates to a method of sealing a shipping case constructed of fibre board or equivalent material. It is the custom now for the trade to use either a slotted end container or else a recessed end container. However, there has recently been introduced the flush-end three-blank container such as shown in my Patents No. 1,452,588 and No. 1,375,127 These containers, known as the Bliss Nos. 2

l and 4, are making rapid strides in supplanting the slotted end container and the recessed end container for the reason that they are more economical containers in the way of material required tomake them and are much stronger and more desirable than the recessed end container.

However, a container of this three-blank type, in order to get the best results In labor economy in setting it up, requires the-use of an expensive stitching machine which w1ll simultaneously stitchlboth' the end blanks on each end. Small shipper's do not feel warranted in undertaking the expense of the installation of the double-headed stitcher. It is the object of the present invention to provide a shipping case which has nearly all the advantages of the Bliss Nos. 2 and 4 boxes, and yet eliminates the necessity of a double head stitcher in setting up and sealing the case. Furthermore, the case is a two-blank case in which the blanks may be sewed together at the mill on a. double head stitcher so the shipper has a complete box all sewed together ready to set up. This is a great'advantage in handling, in the case of small shippers.

The present application is a division of my application Serial No. 685,097, filed January 9, 1924.

tube 'by what is known as a manufacturers under the end blank e.

Fig. 15 is a perspective of the end loader before sealing.

Figs. 16 and 1'1 are plan views of the two blanks of the top loade w \l Referring to Figs. 1 and 2, it will be seen that two blanks are employed, each com ris-. ing three walls sothat the two blanks orm the necessary six walls of the case. Three of the s1de walls a, b and c are formed by what I call the major blank. The other side wall (I and the two end walls e and f are formed 7 b the other blank, which I term the minor b ank. In the recessed end case andin the slotted end container, the four walls of the main blank are sewed together in a collapsible seam. I propose to haveemy case sewed together in a collapsible tube in the same wa but two'manufacturers seams are require These are formed by the two manufacturer's seam flaps g and h, which are preferably" on the major blank so that the tube may be stitched by a double head stitcher but which.

could obviously be on the side 0 the wallat l l I of the minor blank but if here located would result in considerable waste of material and would not be stitched by a double head stitcher. The mill can stitch the manufacturers seam flaps h and g to the side wall d as shown in Fig. 5; this will make a collapsible tube having the two end walls 0 and f permanently secured thereon and which can be secured in place by the aid of the flaps a, b,

and a, and a", b, and a..

No ditficultv will be found in sewing the first end wall f to the flaps a 1) ad 0* as shown in Figs. 4 and 5; this can be easily done with any form of straight anvil that can be inserted in the end of the box. The end flaps may be secured on the inside or outside; this is a matter of indiflerence. It will be noticed, however, that only three flaps have to be stitched in place as compared with four fla s on the recessed end box and on the Bliss o. 2 and No. 4 boxes. The reason for this is that the end blank is already integrally united with one of the sidewalls.

In Fig. 3, I have indicated how the case may be sealed. The endflap b is turned in A blade anvil k is then inserted and the stitches 1, 2 are taken to unite the end wall e with the 13p 6, care being taken to take stitch 1 far enou away from the corner to permit the bl e 3and4 1 anvil to be inserted in position is, shown in the drawings. The flap a may be turned in on the inside or it may be on the outside of the end wall 6; stitches 5, 6, 7, 8 and 9 are taken with the aid of the blade anvil in the osition designated In. These two positions and k of the blade anvil require only one insertion and withdrawal of the anvil so that they are stitching that has been required by the shipr is nomore than required for the well nown slotted end container, yet the saving in material over the slotted end container is relatively greater, depending of course, upon the dimensions of the box it will approximate somewhere in the neighborhood of 20%. The case in its final form has flush ends 270 degrees on the outside and 90 degrees on the inside with clear corners, thus obviating many objections connected with the recessed end case. In Figs. 11 to 14 inclusive and 16 and 17 I have shown a top or side loader. Here the minor blank containstwo side walls m and n at its ends, while the major blank has two side walls 0 and p at its end. The end walls 9 and r are with the top loader in the middle of the minor and major blanks. The flaps 0 p 0 g and p are the securing flaps, and the flaps 0 and p may be folded either inside or outside the cover wing the same as the correspondin flaps a and 0 The manufacturers seam flaps s and t are not as long for a box of the same dimensions. However, the box is set up and sealed in practically the same way as is shown in Figs. 11 and 12.

It will be seen that the invention affords a method of sealing a shipping case wherein one end only need be stitched to finally seal the case. By the use of the methodless ex-' pensive stitching machinery equipment is re quired, in that it is not necessary to have a socalled double header stitcher for handling two ends of the case simultaneously. This is especially advantageous for small shippers whose business does not warrant the obtaining of the more expensive stitching machinery. Moreover-,1) this method, the use of shipping cases of t e type shown in the drawings herein, which has many of the desirable characteristics of the so-called flush end cases, or the use of three blank cases, whichmay also be sealed by this method, is made more feasible.

What I claim is:

1. The method ofsealing a fibre board shipping case which has two op osite walls provided with sealin fla an two other opposite walls, one o WhlCh is provided with a relatively narrow cover flap, and the'other of which is rovided with a cover wing for covering su stantially the entire case, which method comprises. placing a blade anvil under the cover wing and cover flap, driving stitches through the wing and the flap to secure them together, placing the anvil under thecover wing and one of the sealing flaps, driving stitches into them to secure them together,

relatively narrow cover flap, and the other of which is rovided witha cover wing for covering su stantially the entire case, which method comp-rises inserting a blade anvil under the cover win and cover flap, driving stitches through t e wing and the flap to secure them together, inserting the anvil under the cover Wing and one of the sealing flaps, driving stitches into them to secure them together, inserting the anvil over the said cover flap and under the cover wing and the other sealing flap and then driving stitches into the cover wing and said flap to complete the sealing of the case.

3. The method of sealing a fibre board shipping case, which has two opposite walls provided with sealing flaps, and two other opposite walls, one of which is provided with a relatively narrow cover flap, and the other of which is provided with a hinged cover wing which is of sufficient size to be lapped at its edges and free end by the sealing flaps and the cover flap respectively when all are.

folded, which method comprises the insertion of a blade anvil underneath the cover wing and disposing of the anvil, first, so that a portion of the anvil underlies the cover wing near its free end, second, so that a portion of the anvil underlies the wing near one edge and third, so that a portion of the anvi underlies the wing near the other edge, and securing the cover flap and the two sealing flaps to the cover wing in the order named by driving stitches into the cover wing and the cover and sealing flaps when the anvil is properly positioned with respect to the flap.

4. The method of sealing a fibre board shipping case which has two opposite walls provided with sealing flaps, and two other opposite walls, one of which is provided with a stitches into the cover Wing and cover flap, disposing the anvil so that it underlies one sealing flap driving stitches into the sealing flap and cover wing, removing the anvil and reinserting it over the cover flap and under the cover wing and second sealing flap, and

driving stitches into this second sealing flap and cover wing to complete the sealing of the case.

5. The method of sealing a fibre board shipping case which has two opposite walls provided with sealing flaps, and two other opposite walls, one of which is provided with a relatively narrow cover flap, and the other of which is provided with a cover wing for covering substantially the entire case, which comprises inserting a blade anvil under the cover wing and the cover flap, driving stitches into the wing and flap to secure them togetheijshifting the position of the anvil so that a portion thereof underlies one of the sealing flaps, driving stitches into the cover Wing and this sealing flap, withdrawing the anvil and reinserting the same underneath the cover wing and the other sealing flap and driving stitches into the wing and this flap to complete the sealing of the case.

6. The method of sealing a fibre board shipping case which has two opposite walls provided with sealing flaps, and two other opposite walls, one of which is provided with a relatively narrow cover flap, and the other of which is provided with a cover wing for covering substantially the entire case, which method; comprises inserting a blade anvil under the cover wing and the cover flap, driving stitches into the wing and flap, shifting the anvil with respect to the case so that the end thereof moves under one of the sealing flaps, driving stitches into this sealing flap and the cover wing as the movement of the anvil progresses, removing the anvil and reinserting it under the cover wing and the other sealing flap and driving stitches into the wing and this fiapto complete the sealing of the case.

7 The method of sealing a fibre board shipping case which has two opposite walls provided with sealing flaps, and two other 0p 0- site walls, one of which is provided wit a relatively narrow cover flap, and the other of which is provided with a cover wing for covcring' substantially the entire case, which method comprises placing a blade anvil under the cover wing and cover flap, driving stitches through the wing and the flap to secure them together, positioning these stitches to leave a space in which there is no stitch for later insertion of the anvil between the wing and flap, placing the anvil under the cover Wing and one of t-hesealing flaps, driving stitches into them to secure them together, placing the anvil under the cover wing and the other sealing flap by inserting the anvil over the cover flap and under the cover wing in the space previously provided therefor, and then driv ing stitches into them to complete the sealing of the case.

In testimony whereof I afiix my signature.
